If you’re hiring at scale for graduate, apprenticeship, internship or high-volume operational roles, you’ve likely felt the same pressure recruiters everywhere are describing. There are more applications than ever, and less time to tell a strong candidate from a well-written one.
In the UK, assessment centres have been a standard part of the answer to this for decades, particularly in graduate recruitment. In the US, they’re used far less often. Hiring here has traditionally leaned on individual interviews and faster, more decentralised decision-making. That’s starting to change, and it’s worth understanding why.
(For more on how that gap came about, see our article on why the UK uses assessment centres more than the US.)
Early careers and high-volume recruitment look different on paper, but they run into the same wall: a large number of candidates who all need to be evaluated fairly, quickly, and on genuinely comparable terms.
Two things make this harder than it used to be. Application volumes have climbed sharply on both sides of this. Graduate and apprenticeship schemes now routinely draw thousands of applicants for a handful of roles, and operational, retail and customer-facing employers face the same pressure from a different direction: hundreds of broadly similar vacancies that need filling quickly, often on a rolling or seasonal basis. Either way, manual screening and one-off interviews don’t scale without slowing down or cutting corners.
At the same time, AI has made it easier for candidates to polish CVs and application answers, which weakens exactly the signals recruiters have traditionally relied on to filter a large pool down to a shortlist.
More candidates and a less trustworthy early signal is pushing US recruiters toward the same conclusion UK graduate recruiters reached years ago. You need a structured way to see what candidates can actually do, not just what they can write about themselves.
An assessment centre puts every candidate through the same set of exercises, evaluated against the same criteria, usually by more than one assessor. For early careers and volume hiring specifically, that structure helps in three ways.
It gives candidates with limited experience a fair way to show potential. A CV rewards past achievement, which is exactly what early careers candidates don’t have much of yet. An assessment centre lets them demonstrate how they think, communicate and handle unfamiliar situations instead.
It makes decisions defensible at scale. When you’re making dozens or hundreds of similar decisions in a single hiring cycle, using the same exercises and scoring criteria for every candidate matters, both for fairness and for being able to explain a decision later if it’s ever questioned.
It’s also more workable once run virtually. This isn’t the main point of this article, but it’s worth saying plainly: a virtual assessment centre removes the venue, travel and scheduling constraints that made running one for hundreds of candidates impractical in the past. That’s a large part of why the format is realistic for high-volume hiring in a way it wasn’t a decade ago.
It holds up when hundreds of similar decisions need making quickly. High-volume recruitment isn’t just early careers hiring at a bigger scale. It’s often filling dozens of near-identical roles across multiple sites or shifts in a short window, and running everyone through the same structured exercises keeps that pace from turning into inconsistent, rushed decisions.
In practice, an assessment centre rarely stands alone. It’s one stage in a wider process built around the numbers involved.
An earlier, lighter stage usually does the first filter. Many organisations use a structured or video interview ahead of the assessment centre, so recruiter and assessor time on the centre itself is spent on a shortlist rather than the full applicant pool.
Exercises are chosen for the role, not just for tradition. Group exercises, case studies and role-relevant tasks are picked to reflect what the job actually involves, rather than running the same generic activities regardless of the role.
Assessors are trained and calibrated beforehand. Because more than one assessor is usually involved, a short calibration session before the day, agreeing what a strong answer looks like, keeps scoring consistent across the group.
And technology carries the coordination load. Once virtual, a platform can hold every candidate’s timetable, activity briefs, scoring criteria and evidence in one place, which is what makes running one across a large cohort manageable rather than a logistical strain on the recruitment team.
The hesitation US organisations have historically had about assessment centres, that they’re costly, complex to run, or simply not how hiring is done here, was a reasonable read of the format when it meant hiring a venue and flying in assessors. It’s a much harder argument to make now that assessment centres can be run virtually, at a fraction of the cost and logistical overhead.
At the same time, the underlying pressure hasn’t gone away. US employers are moving toward skills-based hiring for much the same reason UK employers have leaned on assessment centres for years: a CV and a single interview aren’t enough to evaluate a large pool of similarly qualified early careers candidates with confidence.
It’s not only an early careers shift either. US employers running high-volume operational or seasonal hiring are under the same pressure to make fast, consistent decisions across large candidate pools, which is exactly the problem assessment centres were built to solve.
For teams hiring at volume or building out an early careers programme, an assessment centre isn’t a UK hiring quirk to import for its own sake. It’s a structured answer to a problem every high-volume recruiter recognises: how do you give a large number of candidates a fair chance to show what they can do, without the process falling apart under its own weight.
